BIM Cost Estimation with DDC CWICR Generate accurate cost estimates from BIM models using AI classification and the DDC CWICR construction cost database. Business Case Problem : Traditional cost estimation: - Manual and time-consuming (weeks for detailed estimate) - Subjective and inconsistent between estimators - Requires specialized knowledge - Difficult to update with design changes Solution : Automated BIM-to-cost pipeline: - Extract quantities directly from model - AI classifies elements to work items - Vector search finds matching prices in CWICR - Complete estimate in hours, not weeks…
